Does anyone know why the Space Shuttle Atlantis poster does not include the flight crew patch of STS-135?

The wiki link is to an outdated version. Not only was the STS-135 emblem added, but the orbiter itself was corrected to be a real photo of Atlantis (as opposed to a manipulated photo of Discovery). You can see the final version hanging in the firing room here: http://mediaarchive.ksc.nasa.gov/#/Detail/19957
